Two people have been arrested on suspicion of murder of a man in his 50s in Great Yarmouth.
Norfolk Constabulary said it was called to a property on South Market Road at 10.20pm on Wednesday night after receiving reports a man had been stabbed.
The victim was found with "serious injuries" and taken to the James Paget Hospital by ambulance, but died shortly after arrival.
A man aged in his 60s and a woman in her 50s, both from the Great Yarmouth area, were arrested on suspicion of murder and taken into custody for questioning.
Chief Superintendent Chris Balmer said: "Clearly we are still in the early stages of our investigation and our inquiries remain ongoing.
"However, it appears that the suspect and the victim were known to each other and we do not believe there to be any threat to the wider public."
